| 摘 要： | 论述了兖州煤田太原组主要成因相的特征和沉积组合类型，分析了富煤带的形成、分布及其与下伏成因相的关系，也分析了海平面变化对成因相的影响和沉积体系的演化方向，并利用标志层划分了分析单元（相当于层序地层中的Ｐａｒａｓｅｑｕｅｎｃｅ），以单元为分析和编图的基本单位研究了兖州煤田的聚煤规律

| Abstract: | The characteristics of main genetic facies and the types of sedimentary associations of Taiyuan Formation in Yanzhou Coalfield are expounded.The formation and distribution of the coal rich unit and its relationship with the underlying genetic facies,as well as the influence of eustatic change of sea level on the genetic facies ,and the evolution of the sedimentary system are analyzed .Using the marker beds the analytical elements (corresponding to the paresequences in the sequence stratigraphy)are divided,and taking the analytical elements as the basic untits for the analyses and mapping,the coal accumulation regularities of the Yanzhou Coalfield are studied. |

| Keywords: | genetic facies sedimentary environment coal accumulation regularities Taiyuan Formation Yanzhou Coalfield |
